Brief Summary:
The purpose of this study is to better understand whether and to what extent the activity of immune cells in blood varies over time under normal conditions as assessed in healthy subjects. Results of this study will provide the foundation for helping us evaluate changes in immune cell activities in response to surgery and drugs used in anesthesia. The overall purpose of our research is to understand immune health in the context of anesthesia and surgery.

Observational Model: Cohort
Time Perspective: Prospective
Official Title: Evaluation of Immune Signaling Networks in Healthy Human Volunteers
Study Start Date : August 2012
Actual Primary Completion Date : July 2013
Actual Study Completion Date : July 2013

Primary Outcome Measures :
  1. Numerical and functional changes of circulating immune cells over time in healthy individuals [ Time Frame: Day 1, Day 2, Day 7, Day 28 ]
    This is an exploratory study. Numerical and functional (phosphorylation of signaling molecules and transcription factors) behavior of all circulating immune cells will be captured. Blood specimens collected at referenced time points will be analyzed with mass cytometry.
